Product Summary

The LM4040C30 is a shunt voltage reference. It is a versatile, easy-to-use reference that caters to a vast array of applications. The LM4040C30 offers low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures. The LM4040C30 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. The applications of the LM4040C30 include Data-Acquisition Systems, Power Supplies and Power-Supply Monitors, Instrumentation and Test Equipment, Process Controls, Precision Audio, Automotive Electronics, Energy Management, Battery-Powered Equipment.
